14/12/2014  This is a two part diagram I have drawn of a standard milling process for china clay, showing both side-on and top-down views. A clay mill consisted of an upright cylinder containing various shapes and sizes of rotor blades that would act to disintegrate the clay pellets. Clay would be fed into the bottom of the mill, along with hot air from an indirect air heater. Clay entering the mill would be

The Buell dryer was first developed by English China Clays for their china clay processing plants in Cornwall. The Buell dryer is a multiple hearth direct heated industrial dryer (commonly known as a turbo dryer) that has modified for drying china clay.

Mining Waste Products - University of Exeter

The early working of china clay was by hand, the river sediment was removed, and then diverted river water was used to separate the coarse sand from the clay, fine sand and mica; a process referred to as ‘breaking in the stream’. The coarse sand settled and was subsequently removed and dumped elsewhere, whilst the remaining clay, fine sand and mica was allowed to settle. The waste

11.25 Clay Processing

Mined fire clay first is transported to the processing plant and stockpiled. In some cases, the crude clay is weathered for 6 to 12 months, depending on the type of fire clay. Freezing and thawing break the material up, resulting in smaller particles and improved plasticity. The material then is crushed and ground. At this stage in the process, the clay has a moisture content of 10 to 15 percent.

China Clay Processing in Cornwall- Mining, Refining and

The steam from the dryer enters the base of a large cylindrical vessel, and passes through a fine mist of china clay slurry. Clay dust particles suspended in the steam get caught in the mist of clay slurry. The slurry drains out at the bottom, while the “scrubbed” steam leaves through the stack. The clay slurry is then pumped to the filter presses. Wet scrubbing had the side effect of pre-heating the clay slurry as
